THROTTLE GONTBGL EUR E/LO'IOR-VEHICLES.

To all whom it may concern Be it known that l, JONATHAN M. CHENEY, a citizen otthe United States, and a resident of Ashland, in the county of. Grafton and State of NewHampshire, have invented certain new and useful Improvements in Throttle Control for Motor-Vehicles, of which the following is a specifica tion.

This invention relates to the means for. controlling the throttle valve of the carbureter of internal combustion engines for motor.vehicles, the invention relating espe cially to improvedmeans whereby the throttle may be controlled either by the hand or foot of .the user.

The object of the invention especially is I to provide means adapted to the Ford. cars are located at its in which the steering post is at the left of the car while the carbureter and its throttle I or near the right.

.gllhe' invention consists in the improvements which 1 will now proceed to describe and Clai the accompanying drawings :-F igure 1 'is aplan view of so much of a Ford car having my improvements attached thereto, as-is necessary for an understanding of the mechanism. Fig. 2 represents a section on line 2'2 of Fig. 1. Fig. 3 is a detail view of the parts carried by the foot-board of the car, looking from the line 3-3 of Fig. 2, and omitting the body and foot-board of the car. Fig. sll-isa vieW similar to a portion of Fig. 2,- on a larger scale. Fig. 5 is a perspective detail illustrating the lost motion connection hereinafter described.

Q41 portion of the body of the car is illustrated at 10, the usual foot-board being indicated at 11. The post 12, steering wheel 13,

steering spindle 14, and the throttle spindle 15 are illustrative. of the type employed in the I carburetor throttle,

the Ford cars. The spindle 15 has an arm 16 se uredto it, and a sleeve 17 having a swipe]. connection with said arm as best lllLlStI'iLtBd in Fig. 5. Slidablymounted'in the sleeve 17 is a rod 18 having an end which projects through the sleeve provided with a suitable stopwhich is illustrated as consisting of a bent end 19. The other end of the'rod 18 isconnected to'an arm formed on a yoke piece 20 which is secured to the stem 21 of the carbureter throttle vdlve. When the hand lever 35 of the spindle 15 is operated in the usual direction to actuate the sleeve 17 is Specification ofiLetters Patent. Application filed. Deeember 4, 1913. Serial No. 804,681.

; stop 19, and sleeve Fig. ,5 without any resistance being by the usual hand control devices. Provision for lost motion/is necessaryat some part of the mechanism, in order to permit the foot resistance by the hand control devices. sleeve 17 and the rod 18 constitute a twor teatea o e. ea, rare.

- moved so that it acts upon tht stop 19 to pull the rod 18 in the directionindicated by the arrow in Fig. 5, while the lost motion connection provided by means of the rod 18, 17, Will permit therod 18 the direction of the arrow in to be shifted in caused,

control mechanism to be operated Without The part connection between the spindle arm 16, and the valve stem arm or yoke piece, the part 18 of said connection being movable in one direction independently of the other part 17, and the two parts being provided with complemental'abutments which cause their movement in unison in direction. One of said abutments is the bent end 19, and the other is the end of the sleeve 17 which bears on said bent end. It is obvious that a two-part connection, one part of which ismovable independently in one direction, the two parts being caused to more in unison in may be made in difierent ways.

I will now describe the foot control devices which' include a plate 22 secured to the foot-board 11 .as by suitable screws, said plate having a grooved portion 23 providing a bearing for a rock shaft 24 having a pedal 25 at one end and an arm-26 at the other end, said arm projecting downwardly through a small slot 29in the foot-board. The hearing plate 22'and the .rock' shaft are .of such length as to provide for the pedal being located in convenient proximity for the person operating the car, and sitting behind the hand wheel 13, while the connections with the other end of the shaft 24 are at the right to correspond with the location of .the carbureterand its throttle. v

The bearing plate 22 enables the rock shaft to be operatively mounted in position without requiring any alteration of the foot board other than making the small slot 29. In order that the rock shaft may be kept properly lubricated, the plate 22 may have Erie ormore oilingholes 27 as indicated in The arm 26 is connected by means of a rodg with the yolge piece 20,which in this embodiment of the invention has two arms,

on'e engaged with the rod 18, and the other the opposite direction,

the opposite 1,1 mess with the rod 28, and the parts are held yieldingly in the initial positions illustrated in Figs. 1 andfl by means of a suitable spring 30 connected. at one end. to the pivotal connection of the arm 26 with rod 28, and at the other end with an arm 31 of a bracket secured to the under face of the foot-board. 11, said bracket having a log projecting behind the arm 26 to serve as a limiting stop to hold the parts in their initial positions It will now be understood that the person operating the machine, and having one foot upon the pedal 25, may actuate the rock shaft so as to cause the-connecting rod 28 to shift the throttle valve stem in the same direction as .that which is imparted to it when tliehaind throttle spindle -is 0 erated, actuation by means of the pedai 25 simply caiising the rod. 18 to shift in the di- 20 rcction of the arrow in big. 5 Without trans mitting any motion to the arm 16 and spin dle 1-5 It em now be seen that the hand-controlled spindle 15, the footcontrolled rockshaft 24:, and the rods 18 and 28, directly connecting the arms of said spindle and rock-shaft with the throttle-valve stem, con sti'tute a very simple and effective hand and foot controlled throttle valve operating mechanism which may be easily applied to Ford car Without modification or alteration of the car, other than making the slot 29 in the foot-board, attaching the yoke piece 20 to the valve-stem, and applying the sleeve 17 to the rod 18. The rod 18 and spindle-arm 16, as here shown, are the same as those now used in the Ford car to connect the spindle 15 With an arm on the valve-stein the bent end 19 of said rod be'ingadapte l to enter 40 the orifice in the arm 16; hence, the only change from the Ford construction required at this point, is the removal of the bent end 19 fromthe arm 16, and the application of the sleeve 17 to the rod 18, said sleeve having a swivel connection With the arm 18, as above stated. The parts of said mechanism and the throttle valve are adapted to he yieldingly held. in their initial positions by a single spring 3 0.Which simultaneously returns the valve, the spindle, and the rock shaft, to their starting positions, and yield ingly presses one of the ahove-mcntioned ahutinents against the other when pressure is removed from the hand lever 35, or the pedal 25. i

It is tobe understood that I do not limit myself to the exact details of construction illustrated and described, but intend to include Within my invention all such modifications ormechanical equivalents as fall Within the terms of the appended claims. I clairn:-
